10 Claims.

ferent portions of a lamp in a manner to insure efficient performance of the radio receiving circuit and at the same time render it possible to obtain wide variations of artistic lamp designs.

.Another advantageous feature of the present invention resides in the provision of a combined lamp and radio receiving set embodying improved means for actuating the several controllable instrumentalities of the radio receiving circuit, such as the variable condensers and the rheostat for controlling the volume of the radio receiving L set.

A further object of the present invention resides in the provision of a combined lamp and radio receiving set wherein the variable condensers are housed in the base of the lamp in a manner to occupy the minimum height and wherein the condensers are operated as a unit by means of a control conveniently positioned with respect to the base of the lamp.

The foregoing, as well as other objects, will be :3

Figure 16 is a fragmentary sectional view through the base portion of a combined lamp and radio receiving set constituting still another embodiment of this invention.

Referring first to the embodiment of the invention illustrated in Figures 1 to 10, inclusive, it will be noted that there is illustrated in Figure 1, a relatively small artistic table lamp 30 hav ing a base 3| supporting a vertical pedestal 32 and having a shade 33 carried by the pedestal 32 at the upper end thereof. In the present instance, one portion of the radio receiving apparatus is housed within the base 3|, another portion is housed in the vertical pedestal 32 and still another portion is arranged within the lamp shade 33.

Although it is to be understood that the specific parts of the radio receiving apparatus housed in the aforesaid sections of the lamp may vary to suit existing conditions, nevertheless, for the purpose of illustration, I have resorted to the following arrangement. Upon reference to Figure 10, it will be noted that the radio receiving circuit, selected herein for the purpose of illustrating the present invention is, of the superheterodyne type and the parts thereof contained in the area defined by the character A are housed within the base 3! of the lamp, while the parts of the circuit contained in the area defined by the character B are located in the vertical pedestal 32 of the lamp, and the instrumentalities of the circuit contained in the area defined by the character C are located in the shade 33 of the lamp.

In order to illustrate the ingenious manner in which the various parts of the radio receiving circuit are compactly arranged in the several sections of the lamp, reference will be briefly made to the various units of the receiver included in the areas defined by the characters A, B and C. Referring again more particularly to Figure 10, it will be noted that the base 3| of the lamp houses one stage of radio frequency including an RF coil 34 and a tube 36 of the 6 K7 type. The base 3| of the lamp also includes the first detector and oscillator stage including a detector coil 31, a variable condenser 38 and a pentagrid converter 39. Also in the base 3| of the lamp is the intermediate stage including a variable condenser 40 for tuning the primary winding of the intermediate coil, and a second variable condenser 4| for tuning the secondary winding of the intermediate coil. In addition, the base 3| of the lamp includes the oscillator coil 42 and a variable condenser 43 for tuning the primary winding of the same. I

In the present instance, the vertical pedestal 32 of the lamp encloses the tube 44 for the intermediate stage, a second detector coil 45, variable condensers 43 for respectively tuning the primary and secondary of the second detector coil, and the second detector tube 41. The power pack defined by the character C is housed within the lamp shade 33 and includes a full wave rectifier tube 48 and an audio tube The problem of compactly arranging the several parts of the radio receiving apparatus in the base and pedestal of the lamp without the danger of overheating the insulation associated with certain of said parts, is J.

solved by locating the power pack in the shade of the lamp where the heat radiated by the rectifier and amplifier tubes may be readily dissipated.

One of the principal features of the present invention which contributes materially to compactly arranging in the base 3i of the lamp the instrumentalities of the receiving circuit con tained in the area A consists in the unique arrangement of the variable condensers and the manner in which the latter are operated. Upon reference to Figure 6 of the drawings, it will be noted that the variable condensers 35, 38 and 43 are each formed of two complementary sections and the latter are symmetrically distributed in the base with respect to the vertical center line of the lamp. By forming each of the condensers of two complementary sections and by distributing the sections in the above manner, it is possible to minimize the height of the base of the lamp so that the latter will not present a cumbersome or bulky appearance. Each of the condensers is preferably identical in construction and comprises a pair of stators 52 and a pair of rotors 53 rotatably mounted with respect to the stators in a manner to be presently set forth.

In order to simplify the control of the radio receiving apparatus, common means is provided for simultaneously rotatably adjusting the rotors 53 01 each of the condensers 35, 38 and 43. The manner in which the foregoing is accomplished will be understood upon referring to Figures 6 t0 9, inclusive, wherein the reference character 54 designates a fiber driving gear mounted for rotation substantially centrally of the base 3| of the lamp and arranged in mesh with the three gears and an amplifier 49 comprising a speaker 50 designated in Figure 7 by the reference characters 55, 56 and 57. The gear is secured to the shaft 58 of one of the rotors of the variable condenser units 3, while the gear 53 is secured to the rotor shaft 59 of one of the rotors of the variable condenser unit 38, and the gear 5'! is secured to the rotor shaft 60 of one of the rotors of the condenser unit 43. Thus, it will be observed that one rotor shaft of each pair is driven by the drive gear 54 and, in order to impart the same degree of rotation to the other rotor shaft of each pair, suitable gears 6| are secured to the latter shafts in mesh with the gears 55, 55 and 5'l'respectively. The gears 6| are of the same size as the gears 55 to 51, inclusive, so as to insure simultaneous movement of the rotors at the same rate of speed, and the axes of the gears Bl are so located that the latter gears do not mesh with the drive gear 54. Adjustment of the rotors of the several variable condensers is effected through the gears by means of a control 62 having an arm 63 secured as at 54 to the drive gear 54 and extending laterally outwardly from the latter gear through an arcuate slot 65 formed in the side wall of the base adjacent the bottom of the latter. The other extremity of the arm 63 is provided with an upwardly extending pointer 66 and a knob 51 is secured to the pointer in a position to be conveniently grasped by the operator. The pointer 66 is for the purpose of indicating the usual indicia applied to a band 68 which, in turn, is secured to the side wall of the base above the slot 65.

Referring now more in detail to the particular construction of the lamp selected herein for the purpose of illustration, it will be noted that the same comprises a base plate 69 secured to an auxiliary non-metallic base 10 through the medium of the fastener elements H. The auxiliary base 10 is positioned in spaced relation to the base 69 through the medium of the spacers 12 surrounding the, fastener elements H and of sufficient length to provide the space 73 between the two plates required to house the gearing previously referred to as operating the rotors of the variable condensers 35, 38 and 43. Upon reference to Figure 9, it will be noted that a fastener element 14 serves to secure the central portion of the base plate 69 to a disc 15 held in spaced relation to the plate 69 by means of a spacer 16 located within the space 73 and having a length approximating that of the spacers 12 so as to support the disc 15 in the plane of the auxiliary base plate 10. In the present instance, the spacer 16 is provided with a cylindrical exterior surface forming a journal for the drive gear 54 of the variable condenser gear train.

The manner in which the remaining gears of the aforesaid train are mounted is illustrated in Figure 8. In this connection, it is to be noted that Figure 8 shows only the pair of gears 51 and BI directly associated with the Variable condenser 43, and it is to be understood that the remaining pairs of gears are mounted in an identical manner. In detail, the gears 51 and El are secured to the lower ends of the variable condenser rotor shafts 60 and BI, respectively. These shafts are suitably journalled in metallic inserts 11 secured in the auxiliary base plate 10 and the portion of the shafts extending above the auxiliary base form supports for the complementary variable condenser rotors 53. The rotors 53 are provided with bushings 19 secured to the rotor shafts and carrying the rotor plates 80. The rotors 53 are grounded by spring metal fixedly sefasteners 83 having the outer ends cured to the auxiliary base 10 and having the inner ends disposed between the latter base and the lower ends of the bushings 19. As shown in Figure 8, the inner ends of the fingers 83 are shaped to constantly urge the rotor shafts in an upward direction and thereby maintain the required relationship between the rotor blades 80 and the cooperating stator blades of the variable condenser. Thus, it will be apparent that each of the variable condensers, employed in the construction, is formed of two complementary sections cooperating to afford substantially double the capacity of a single condenser unit of the same height. In other words, the above construction renders it possible to house condensers of the required capacity in a relatively small ver tical space and this is of extreme importance in the present illustrative embodiment of the invention, due to the limited vertical space available in the base 3| of the lamp.

Upon reference to Figures 3, 5 and 6, it will be noted that provision is made to shield certain parts of the radio receiving circuit from other parts of this circuit. This is accomplished herein by arranging the vertical shields 84 in the base 3| having the lower ends extending through the auxiliary base plate Ill and secured to the underside of the latter by means of the horizontal plates 85. The particular number of shields and the arrangement of the latter in the base 31 will, of course, depend upon the nature of the portions of the circuit housed in the base. With the specific arrangement shown in Figures 1 to 10, inclusive, the shields 84 are preferably located in the manner clearly illustrated in both of Figure 5 and 6 to shield from each other the several parts of the radio receiving circuit shown in these figures.

Cooperating with the base plate 69 to form a housing for all of the parts of the radio receiving apparatus in the base 3! of the lamp is a casing 85 secured at the lower end to suitable brackets 86 by fastener elements 81 having the additional function of securing the indicia band 38 to the side wall of the casing. The bracket 86 are secured to the auxiliary base plate in the manner shown in Figure 8 and the fastener elements 8! are preferably the only means securing the casing 85' in place, with the result that the same may be readily removed when access to the in radio receiving parts in the base is desired. The contour of the casing 85' is shown in Figure l and as will be observed from this figure, the top wall of the casing is apertured to provide for extending the combined volume and on and ."5

oil switch control 88 therethrough. It will, of course, be understood that the knob of this control is readily detachable in order to permit the casing 85' to be removed when desired. The top wall of the casing 85 is also centrally apertured, as at 89, to receive a bushing 99 having the lower end sleeved over. the disc 75 and permanently secured to the latter. The upper end of the bushing 99 projects above the top wall of the casing 35 and is normally concealed by a collar 9| fixedly secured to the casing 95.

Referring now to the peculiar construction of the pedestal 32 of the lamp, it will be noted that the same comprises two eccentrically arranged tubular sections 9?. and 93. The outer tube 92 is formed of two complementary sections for convenience in assembly and the lower end of this tube is sleeved within the collar 9| to seat upon the upper end of the bushing 90, in the manner clearly shown in Figure 1. The complementary sections of the tube 92 are secured in assembled relation at the lower end by the collar 9| and at the upper end by the closure 94, threadedly secured to the stem 95 projecting into the tube 92 through the closure 94.

The tube 93 is supported within the tube 92 eccentrically with respect to the latter so as to provide the maximum space 96 for the electrical conductors 9? required to connect the instrumentalities of the radio receiving apparatus in the base to the parts of the same in the pedestal and in the shade. In detail, the lower end of the tube 93 is sleeved on an enlargement of the disc '15 in the manner shown in Figure 9, and the upper end of the tube 93 is suitably secured to the lower end of the stem 95. It has been previously stated that the intermediate tube 44 and the second detector tube 41 are located in the pedestal 32 and, in the present instance, are housed in the tubular member 93. In order to permit these tubes to be readily assembled with, or removed from, the tubular member 93, the latter is cut away opposite the tubes in the manner designated by the reference character 98. In this connection, it will be noted from Figure 5 that the bushing is also cut away as at H39 in alignment with the cut-away portion 99 in the lower end of the tubular member 93 so as to completely expose the intermediate tube 44 through the tubular member 93.

Referring now to the construction of the lamp shade 33', it will be noted that a housing I9! is secured to the upper end of the stem within the shade I92 and this housing contains the power transformer I93, together with the associated choke coils forming parts of the power pack or speaker unit assembly. The speaker 59 is supported upon the upper end of the housing within the shade I92 and the cone I84 of the speaker is supported, in the manner shown in Figure 1, directly below the perforated disc I95 forming the top of the shade I02. The above construction is such that the shade I92 also acts as a baffle to prevent the upwardly directed colurnn of air from co-mingling with the downwardly directed column of air, and thereby prevents the cancellation of the bass notes.

Upon reference to Figure 1, it will also be noted that the housing llll supports the illuminating bulbs 106, and these bulbs are so positioned with respect to the other instrumentalities housed in the shade as to prevent the same from casting a shadow on the shade. The illuminating bulbs I913 are arranged in switch sockets l0! and the latter are connected to the housing through the medium of tubes E8 of suflicient diameter to permit the electrical conductors to be extended therethrough.

In the embodiment of the invention illustrated in Figures 11 to 15, inclusive, I have shown a different, arrangement of the several instrumentalities of the radio receiving circuit in the base and pedestal of the lamp. In general, the base We cop'ains only the variable condensers of the receiving circuit and the means for actuating the several rotors of the condensers simultaneously. The remaining parts of the radio receiving circuit described in connection with the first form of the invention as being in the base of the lamp are compactly positioned within the pedestal I26, and the latter is divided into three compartments for accommodating these parts. Upon reference to Figure 14, it will be noted that the first detector coil I27, the oscillator coil I28 and the RF coil I253 are located in the compartment I39 and are shielded from. one another by the shield .I3I'. Disposed directly above the compartment I33 is an intermediate compartment I3I and the latter'is adapted to house the pentagrid converter I32, the first intermediate tube I33, intermediate coil I34 and the RF tube I35. As shown in Figure 13, the several tubes in the compartment I3I are shielded from one another and from the coil I34 by the shields I36. The upper compartment I32 is shown in Figure 12 as containing a second intermediate coil I31, a second detector tube I38, a second intermediate coil I39 and a second intermediate tube I 48. The tubes I38 and I46 are shielded from each other, as well as from the two coils, by means of the shields I4I suitably secured within the compartment I32. It will be noted from the above that the circuit in the persent lamp construction differs from the circuit featured in Figure in that it embodies an additional stage of intermediate frequency.

The variable condensers are exactly the same in construction as defined in connection with the first embodiment of this invention and the gearing for operating the rotors of these condensers is also arranged in the same manner previously described. However, the means for simultaneously operating the several rotors of the condensers is slightly difierent and this means is shown in Figures 11 and 15 as comprising a ring I42 supported for rotation about the axis of the drive gear 54 by the rollers I43 secured to the base plate I44 in circumferential spaced relationship. The diameter of the ring is predetermined with respect to the dimension of the base I so that peripheral portions of the ring extend through slots I46 in the several sides of the base permitting the ring to be conveniently engaged by the operator from several sides of the base. Upon reference to Figure 15, it will be noted that the ring is secured to the drive gear 54 by means of a strap I41 so that the rotative movement imparted'to the ring will be transferred to the drive gear 54 and from the latter to the several rotors of the condensers in the same manner described in connection with the first embodiment of this invention. With this construction, the condensers may be controlled from any one of a number of sides of the base and the volume may be regulated by a control $33 similar to the one shown in Figure 1 of the drawings. Attention is called to the fact that in this embodiment, the wave indicating band I42 is secured to the ring I42 for rotation as a unit with the latter to register the indicia thereon with a fixed pointer I43 extending into the window I44. 7

Referring now to the embodiment of the invention illustrated in Figure 16, it will be noted that the condensers I are distributed in the base I5I of the lamp in the same manner illustrated in the first described form of the invention and the rotors of the condensers are simultaneously rotated relative to the stators by means of a central driving gear I52 rotatably supported on the annular wall I53 of the compartment I54. The central driving gear I 52 meshes with suitable pinions I55 which, in turn, are secured to the rotor shafts of the condensers, with the result that these shafts are simultaneously rotated upon rotation of the central driving gear I52. In the present instance, rotative movement is imparted to the driving gear I52 by means of a ring I56 having a di ameter slightly less than the diameter of the side wall I 51 of the base and connected to the driving gear I52 by means of the spokes I53. The ring I56 is, of course, concentrically arranged with respect to the axis of rotation of the gear I 52 and is made accessible for rotation exteriorly of the base by means of a control ring I59 secured to the ring I56 and projecting laterally outwardly through the annular space I60 provided in the side wall I51 of the base.

It will be observed from Figure 16 that the annular space I68 is provided by forming the base I5I of two sections and by securing the sections in vertical spaced relation to each other through the medium of the spacers I6I. The upper ends of the spacers are shown in Figure I6 as engaging the undersides of suitable lugs I62 permanently secured to the upper section of the base I5I and the lower ends of the spacers abut the bottom wall of the lower section of the base. In the present instance, the spacers are in the form of tubes for receiving suitable fastener elements I63 and the latter serve to effectively clamp the two sections of the base in assembled relationship.

It will also be observed from Figure 16 that the combined volume control and off and on switch I64 is supported in the base I5I. This device is operated by means of a ring I65 surrounding the lower end of the pedestal I66 and supported on the top wall of the base for rotation about the axis of the pedestal. The ring I65 is held against axial displacement relative to the pedestal by means of an annular radially outwardly extending flange I66 provided at the lower end of the pedestal and adapted to extend over an annular inwardly extending flange I 61 on the ring I65. As a result, the ring is held in assembled relationship with the lamp and may be rotated about the axis of the pedestal. In the present instance, the ring I65 is operatively connected to the device I64 through the medium of suitable gearing. As shown, a gear IE8 is rotatably supported on the annular side wall I53 of the compartment I54 and is connected to the ring I65 for actuation thereby by means of a pin I69. The device IE4 is provided with an operating shaft I16 having a pinion I'II secured thereto in mesh with the gear I68 so that rotation of the ring I 65 effects a rotation of the operating shaft I'IEI to not only control the volume of the radio receiving set, but to also control the circuit supplying electrical energy to the radio receiving set.

Although a number of different embodiments of this invention have been described somewhat in detail, nevertheless, it will be noted that each modification contemplates installing a complete radio receiving apparatus in a lamp in such a manner that the same does not appreciably restrict the design of the lamp or render the same cumbersome in appearance. In other words, in each of the several embodiments of this invention, the instrumentalities of the radio receiving apparatus are ingeniously arranged to permit the same to be housed in the minimum of space and this is of particular importance from the artistic point of view. It will also be noted that in each embodiment of the invention, the rectifier and amplifier tubes are located in the shade assembly of the lamp so that the heat generated by these tubes will not destroy any of the parts of the radio receiving apparatus sensitive to heat and will not interfere with the compact arrangement of these parts. In addition to the foregoing, it will be noted that I have provided novel control means for the several instrumentalities of the radio receiving apparatus and that this means is of such a nature as to permit the same to be cleverly worked into the design of the lamp.
